Man, you'd be surprised what chefs will do, even the top ones. As in hygene. Ramsay might blow his top on tv when a guy drops a chicken wing on the floor then chucks it back in the fryer, but the reality is very different. If a fillet steak takes 15 minutes to cook, and it goes on the floor between oven and plate, it's more often than not gonna be picked up and put on the plate unless there is a spare fillet they can use. My current head chef is fucking revolting in that regard. Bloody Portuguese. Grated cheese, salad, you name it, if it goes on the floor, it's gonna be used. "What can you do? mains are away" will be his response, plain naaasty.
